Optional Go features

In this section of the book we’re going to talk about two Go features that are relatively new additions to the language: file embedding and generics.

Using these features is completely optional — our application works absolutely fine without them — but they are both useful and worth knowing about.

• File embedding makes it possible to embed external files into your Go program itself.

• Generics can help to reduce the amount of boilerplate code you need to write, while retaining compile-time type safety.

Let’s jump straight in and take a look at them.
